the total length (without caudal), the length of the head three 
times ; head about as high as long; snout as long as the eye, 
the diameter of which is two-sevenths of the length of the head, 
and more than the width of the interorbital space; jaws equal 
in length anteriorly, the maxillary extending to below the ante- 
rior margin of the orbit. Preeorbital and angle of the praoper- 
culum without serratures ; opercles, throat, and isthmus entirely 
scaly ; cheek with four series of scales. The dorsal fin com- 
mences above the end of the gill-cover, and terminates close by 
the caudal: its spines are of moderate strength and length, and 
can be received in a groove; those from the fifth to the ninth 
are the longest, not quite half as long as the head; the last two 
spines are equal in length; the soft dorsal is elevated and scaly 
at its base. The second and third anal spines are equal in length 
and strength, and scarcely longer or stronger than those of the 
dorsal fin ; the soft anal is similar to the corresponding part of 
the dorsal. Caudal fin rounded, nearly one-fourth of the total 
length; without scales, except at the base. Pectoral rather 
narrow, extending as far backwards as the ventral, and shorter 
than the head; the ventral does not reach to the vent. 
Scales with the margin entire; the upper part of the lateral 
line terminates below the middle of the soft dorsal, above the 
commencement of the lower part. 
The jaws, vomer, and a narrow strip of the palatine bones are 
armed with bands of villiform teeth. The dentigerous plates on 
the roof and on the bottom of the mouth appear to have one 
undivided surface, no separate molar teeth being distinct: the 
upper is oblong, slightly taperig in front, rounded behind, and 
somewhat contracted in the middle; the lower is elliptical, 
and there is a smaller transverse plate behind the larger one. 
One specimen, 34 inches long, has been presented to the 
British Museum by Dr. F. Day. It was obtained within the 
hill-ranges of Travancore, on the Malabar coast, where the spe- 
cies does not appear to be very scarce.

By M. F. Maury, LL.D. &c. 1864. 
Tuis is an interesting book for young people who have to learn the 
mutual influences of land, water, and air on the surface of the globe. 
The rivers, lakes, and seas conform to the shape of the ground, and 
their waters are taken up by the circulating air (or winds) to be 
again poured down as rain; and these processes, endlessly modified 
in different regions, and mien different climates, both of zones and 
heights, variously affect the aspect of nature, chiefly through the
